From what you wrote, it does certainly sound as though your experience with the 14 year old girl who bullied you may be at the root of why you are experiencing so much anxiety. And, yes, you may also be experiencing some depression as well, as a result of this experience. What tends to happen is that pathways get established in our brains as a result experiences we have in day-to-day life. And, once these pathways get established, it can be very difficult to get out of them... sort-of like a car driving in a rut in the road. The fact that you were so young when this bullying happened to you, means that you were probably particularly vulnerable to being affected by this experience. It may be that, as you get older, you will find you'll outgrow the anxiety & depression you're experiencing. But, if not, please seek the services of a professional mental health counselor or therapist to help you. I wish you all the best.
